Not really. It gave me the same response as yours for the first time. But then we argued, it explained why it gave me the initial response, and provided me with the better one. It does mistakes, but it'snot all that ignorant.
It is intelligent in some ways, and it not in others. When you correct the request, it will do the right thing. It will also synthesize new answers, it will answer questions never answered to. It is much more organic and creative than just search. I tease it often for very weird questions that google search cannot answer.
If you have set a fixed ISO, then the camera's metering system will try to achieve a target exposure appropriate for that ISO. In this case, the ISO setting is indirectly affecting exposure as it affects the camera's metering. A low ISO setting may also encourage the photographer to add more light to the scene, that's yet another indirect way ISO affects exposure.
If you have set Auto-ISO, then the camera may try to balance exposure with motion blur and depth of field. In this situation, other camera settings may also affect exposure. For instance, if your camera is set to Auto-ISO, full auto, and "portrait mode", the camera may choose a higher exposure, in order to get a shallow depth of field. However, change from "Portrait" to "Sports", and the camera may choose a lower exposure in order to reduce motion blur.
In full manual mode, the photographer typically determines the exposure. While the photographer may be influenced by the ISO setting, this is not always the case. For instance, the photographer may start by choosing aperture and shutter without regard to ISO. Along with subject lighting, shutter and aperture determine the exposure. The photographer may then choose an ISO setting. In such a case, the exposure determines the ISO, and not the other way around.
Back in the days of film, most photographers started by choosing a target exposure, and loaded film with a corresponding speed. Everything from then on was baed on hitting that pre-determined exposure. Now that most of us shoot digital, we are not limited to that workflow. We can prioritize depth of field and motion blur. As our last step, we can set an ISO that matches the resulting exposure.
ChatGPT and similar technologies are basically extremely sophisticated pattern matching systems. They give a predicted answer based on what they have already seen. There is no concept of true of false, just whether it is consistent with what is generally being said.
I'd say set an ISO that is suited to the resulting exposure, although I could agree as stands with one definition of the word match. The definition of match that applies is "make or be harmonious".
Tourists with a camera pre-loaded with ASA 400 film, taking pictures of various attractions during the day and in the evening, do they rely on target exposure or they rely on film latitude and minilab? Or they are excluded on the basis that they aren't photographers?
